DELAWARE, CORPORATION OF PROTECTING- DEVICE FOR AMMUNITION.

To all whom t may concern.'

Be it known that I, Julius SCHIRRA, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and b State of Pennsylvania, have invented cer. tain new and useful Improvements in Protecting Devices for Ammunition, of which the following is a specification.

rlhis invention relates to improvements in protecting devices especially adapted .for protecting the riling bands of ammunition of relatively large caliber.

The rifling band of projectiles is generally of material readily damaged, and when damaged becomes unserviceable for its purpose. Consequently, it is desirable that such band be protected from damage. Devices for this purpose have heretofore been relatively expensive, and where lthe number of projectiles to be protected is large,.the item of cost of the protecting devices becomes serious, especially in view of the fact that this cost becomes practically a total loss even though it be. possible to remove the device Without damaging it. This is due to the fact that these devices are generally removed only at the point where the projectile is to be used, and it would be impracticable to collect the devices and return them to the point of projectile manufacture for obvious reasons. The cost of manufacture, therefore, becomes of importance, it being understood, of course, that the device must be capable of providing the desired protection.

The present invention is designed pai'- ticularly to provide a device of this character which will produce the necessary protection, and which can, at the same time, be manufactured at a low is brought to a minimum, it being understood `that some form of protecting device is absolutely necessary. Another feature is the ability to quickly remove the device so as to reduce to a minimum the time required in placing the projectile into service when it is to be used, it being-obvious that if a lengthy manipulation. of the device-is' re quired, the placing of the projectile-into the S0 piece of ordnance will be correspondingly delayed, a delay which may lprove serious.

In connection 'with' these features, it' is also to be noted that the characterof the protecting device becomes of. 'importance duringv transportation and handling 'of the Specification of Letters Patent.

especially when the number being transported is comparatively large, it being necessar under such conditions, to

bring the projectiles into close proximity in order that a maximum number may be transported, this being especially true in transporting the projectiles from the base of supply to the point of use, generally at a period when time and amount of ammunition being. transported are essentials.

To these and other ends, the nature of whichwill be readily understood as the invention is hereinafter disclosed, said invention'consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings, in which similar reference characters indicate 'similar parts in each of the views, Figure l isa view showing diagranunatically a projectile having a protecting device according to the present invention in position thereon, the view being partlybroken away in order to more clearly disclose the manner in which the .device is applied. Fig. 2 is a section taken diametrically through the device.l Fig. 3 is a detailed sectional view on the line 3-3 of Fig. 2. Fig. 4 is a detailed view showing the ends of the strip forming the device in one form of our invention. Fig. 5 is a view similar to Fig. 2 lshowing a dierent way in which the ends of the stripl are secured together. Fig. 6 is a sectional view taken on line 6`6 of Fig. 5. Fig. 7 indicates a modilied arrangement.

The protecting device of the present invention is-in the form of a band madeof preferred material for the purpose being that known as commercial fiber, a material which is tou h, comparatively light in weight, and a le to resist rou h usage', and at the same time maintain its ape. l

The material is in the form of. a strip; indicated at 10, of suitabledength and Width, this strip havi g oneV side edge turned or bent-inwardly upon itself, as indicated at this edge on the innerside of the band,y where,as indicated in Fig. 1

11, thus placing evice being 'it provides a supporting shoulder 12 whicli is adapted t6 rest upon the upper exposed portion of the riiingzband, the

simply slippedover the end of the projecis adapted to extend on the outer side tile until this shoulder contacts with the rifling band, the skirt-like portion extending over the band.

The ends of the strip are vsecured together'to provide a ring-like conliguration to the device, the drawing indicating two ways in which this may be provided, that shown in Figs. 2 and 3 providing for ready engagement without the use of rivets or other structure, while Figs. and 6 employ a suitable rivet connection.

In the structure shown in Figs. 2, 3 and 4, the ends of the strip are slitted laterally as at 13, the slit at one end extending from the side edge of the strip opposite that of the slit of the opposite end, the bent over portion 11 being foreshortened a distance suflicient to permit of the ready interengagement of the two ends as indicated.

In the form shown in Figs. 5 and 6, but one endv of the 'strip is slitted, the slit extending inwardly from the end longitudinally of the strip, this arrangement providing two portions, the upper one of which of the other end of the strip, while the other portion extends on the inner side. The upper portion, indicated at a is riveted to the opposite end by a ner portion of the rivet being covered by the inturned portion 11 of the opposite end. In this case, the inturned part 11 is removed for a distance equal to the length of portion 10a.'

As shown in Figs. 1-6`inclusive, the strip is preferably provided with a bead-like portion 15 which extends in the direction of' length of the strip. Thisbead-like structure provides a portion which projects o ut- Y erably produced strip form,

wardly beyond the plane of the remainingportion of the device and especially beyond the line of the device skirt, the latter being indicated at 10b. This bead-like structure is adapted to act to retain the skirt out of contact, with any object which may contact with the device under general transporta' tion and handling conditions, thus reducing liability of such contact tending to damage the riing band through pressure placed on the skirt. This bead-like formation is prefwhile thebandis in its and as the material of the strip has suflicient body for the purpose, the beadlike conformation will generally be retained even though it is unsupported. If desired, however, this bead-like conformation may be reinforced by the presence of an element, as in Fig. 7, the element being of suitable material, thaJll shown in this figure being a strandof rope or twine. This particular arrangement increases the projection of the bead and thuspplaces the distance from the outer line of the bead.

As will be readily understood, the blank from which the band is formed can be suitable rivet lllfthe inskirt 10b a greater stamped out and easily manipulated to produce the desired shape. Consequently, the c ost` of manufacture is reduced to a minimum, especially' since the device can be practically completed by machinery. In the form shown in Figs. 2-4, the forming of the blank, the inturning of portion 11, and the rolling of the bead (the latterl also giving the strip its band-like formation) practically completes the operation. Rolling the bead after the portion l1 has been bent in, produces an effect such as shown for instance at 11a. It is only necessary then to engage the ends in the manner indicated in Figs. 2 and 3, to complete the band. In this form, each end has an overlapping and an underlying relation to the opposite end.

A substantially similar practice is provided in the construction of Figs. 5 and 6, this construction adding the necessity for riveting the' ends by the addition of a suitable rivet, `a preferred arrangement being to mploy a split rivet inserted from the outer ace.

As heretofore explained, the devices are simply slipped over one end of the projectile, contact of shoulder 12 and the rifling band limiting the movement in this direction. The skirt of the device preferably has a slight frictioni on the riiing band, thus tending to prevent shifting of the device to expose the rifling band. This is rendered possible in the forms of devices illustrated herein, by reason of the fact that the blanks are of uniform size and the projectiles and bands are of an exact size, so that practical assurance is had that each device will present practically the same frictional engagement with the ril-ling band Without requiring material careful manipulation of the device in its manufacture.l I

The device may be removed by slipping it ofl' the projectile, or, if desired, it may be severed at any desired point, thus releasing it without material delay and without neces sity ofthe use of any special tools.

What I claim is 1. A protecting device comprising an annular band-like memberrhaving an internal shoulder to support the device in position, the body of said member projecting on opposite sides of the plane of said shoulder .to cause a portion of the body to form a skirt adapted to project over the surface be' protected.

2. A protecting device comprising an annular band-like member having an internal shoulder to'support the device in position, the body of said member projecting on opposite sides ofthe plane of said shoulder to cause a portion of the body to form a skirt adapted to project over the surface being protected, said shoulder extending in the direction of peripheral length of the :member.

3. A protecting device comprising an annular band-like member having an internal shoulder, the body of said member projecting on opposite sides of the plane of said shoulder to cause a portion of the body to form a skirt adapted to project over the surface being protected, said member having a peripherally-extending bead-like conformation projecting outwardly beyond the skirt line.

4. A protecting device comprising an annular band-like member having an internal shoulder, the body of said member projecting on opposite sides of the plane of said shoulder to causeI a portion of the body to form a. skirt adapted to project over the surface being protected, said shoulder extending in the direction of peripheral length of the member, said member also having a pcripherally-extending bead-like conformation projecting outwardly beyond the skirt line.

5. A protecting` device comprising a Strip of material having one side portion bent upon itself to form a shoulder spaced from such inturned edge, said shoulder acting to support the device in position, the opposite side portion extending beyond said shoulder and being adapted to'act as a skirt relative to the shoulder.

A protecting' device comprising a strip of material having one side portion bent upon itself to form a shoulder spaced from such inturned edge, the opposite side portion extending beyond said shoulder and being adapted to act as a skirt relative to the shoulder, said member having a periphcrally-extending bead-like conformation to provide a face projecting outwardly beyond the skirt line.

S. A protecting device comprising a strip of material having one side portion bent upon itself to form a shoulder spaced from such inturned edge, the opposite side portion extending beyond said shoulder and being adapted to act as a skirt relative to the shoulder, and means for securing the ends of the strip together to provide a combined overlapping and underlying relation between such ends.
